Every year my mother-in-law's house smells oh so Good!
She burns this little mix of stuff on the stove that is just divine. I always say I am going to make it to pass out to friends and neighbors, and use for myself. Well this year I finally did it, I love it and it is so easy. You just put all the stuff into a pot on the stove and keep it on low, refresh it with water and when it stops smelling do a new batch.
1 small orange
2 tbsp. of cloves
1-3 cinnamon sticks
1 bay leaf
Slice and mix in one quart water, place on low on stove, renew with fresh water.
